Szafir vulnerabilities

Szafir is vulnerable to Path Traversal in the uploaded filename. A man-in-the-middle attacker who can reroute update requests to their server can prepare an arbitrary XML file that will be saved in a location chosen by the attacker. This issue was fixed in version 2.0 build 708.

Szafir and Szafir Weryfikująca are vulnerable to XML External Entity (XXE) injection. When a user signs or verifies a crafted XML file containing a DOCTYPE with an external DTD reference, the parser processes external entities, allowing an attacker to read arbitrary files from the victim's filesystem. This issue was fixed in Szafir version 2.0 build 708. Szafir Weryfikująca is no longer supported (End of Life) and has not been fixed.

Szafir accepts any client or server certificate without performing certificate and hostname validation, allowing HTTPS connections without authenticating the remote server. An attacker can provide an arbitrary SSL/TLS certificate and cause the application to download an update file from their server.
